פירוש על קידושין 39:4

The baraitot both agree that a father may not sell his daughter to his son (I can just imagine how this would play out in my family!). But one baraita says he may sell her to his father.

At the end of last week’s daf we saw a dispute between the rabbis and R. Eliezer—the former hold that he may not sell her to his relative, while the latter holds that he may. So the second baraita agrees with the rabbis, but with whom does the first baraita, the one that distinguishes between the father and the son, agree?
